This Victron Energy SmartSolar MPPT charge controller is the definitive choice for solar enthusiasts managing a 48V battery bank. Perfect for off-grid homes, RVs, boats, and backup systems, it converts every available sun ray into usable power while protecting battery health. At the current price of $100 (down from $1341.25) and with an additional 15% off using coupon code SAVE15, this is your smartest solar investment online.
Maximize solar harvest with lightning-fast maximum power point tracking, even under partial shading.
The VictronConnect app provides real-time data, 30-day history, battery presets, and remote configuration—all at your fingertips.
Program the load disconnect voltage to prevent battery over-discharge and protect your appliances.
Ideal for 48V battery banks in off-grid homes, RVs, marine, and remote monitoring systems. Compatible with most solar panels up to 100V open-circuit. Easily handles solar arrays up to 1400W on 48V systems (see below).
For a 48V battery bank, the 100/20 handles a maximum solar input of approximately 1400W (using 1.25 safety factor). Always confirm panel Voc does not exceed 100V.
Use appropriately rated cables (e.g., 6 AWG) and proper fusing between panels and controller. The controller automatically detects 48V battery voltage.
While this model works for 12V and 24V systems too, it shines in 48V setups where higher voltage reduces cable losses and allows thinner wiring. For 12V/24V, lower wattage panels may be more suitable.
Consider the SmartSolar 100/30 for higher current needs. The 100/20 is the cost-effective choice for 20A loads.

For 48V, the maximum solar input is about 1400W. Ensure panel open-circuit voltage stays below 100V.
Connect your 48V battery bank to the battery terminals, and solar panels (Voc ≤100V) to the PV terminals. The controller auto-detects 48V. Use proper fusing and cable sizing.
This model covers 12/24V as well, but it is especially efficient for 48V because higher voltage reduces current and allows smaller cables. For 12V systems, you might prefer lower voltage models.
I've been using this charge controller for a few months now with my 48V battery bank. It's incredibly efficient, and the Bluetooth app makes monitoring a breeze. The build quality is top-notch, as expected from Victron. Highly recommend.
Works perfectly and the app is really useful. I'd give it 5 stars but it's expensive compared to other options. Still, you get what you pay for with Victron.
Works great.
We installed this at our off-grid cabin where we have a 48V system. It handles our solar panels flawlessly and the Bluetooth lets me check things from inside without going out in the cold. The app is intuitive and shows all the data I need. Very pleased with the purchase.
The controller works well once installed, but the manual is a bit confusing. I had to watch a few videos to get it right. Still, it's a solid product.
This is my second Victron charge controller. They are reliable and efficient. The Bluetooth is a great addition, making it easy to monitor and adjust settings. Worth every penny.
I'm a solar installer and I've used many brands. Victron is hands-down the best. This 100/20 is perfect for small 48V systems. The Bluetooth saves time during setup. My clients love it.
It does exactly what it says. My batteries are always full. The app is nice but could use a few more features. Overall, a great investment.
For the price, this is unbeatable. I got it on sale and used the SAVE15 code for extra discount. The performance is outstanding. My solar yield went up noticeably compared to my old PWM controller.
If you're new to solar, this might be overwhelming. Once configured, it's great, but setting it up took some effort. Bluetooth is a plus.
This controller is amazing. It's small but powerful. The app is user-friendly, and the data is accurate. I recommend it to anyone with a 48V system.
